The conditions are met to use a [1-Proportion Z-Test V
T: TEST STATISTIC
The symbol and value of the random variable on this problem are as follows:
Leave this answer as a fraction.
p-p
If no N is given in the problem, use 1000000
p(1-p)

The formula set up of the test statistic is as follows.:
(Leave any values that were given as fractions as fractions)
=
